1. CHANGE IN THE RESISTANCE FACTOR ADJUSTMENT SETTINGS
2. MEA SURES TO PREVENT T HE A C RELA Y HARNESS FRO M C OM IN G
IN CONTACT WITH THE FAN DUC T
1. Change in the resistance factor adjustment settings
1.Model name: SF-2014/21 14/2214
Z-800, SN-1420/1430 (USA only)
2.General: Problems of RZS folding of the copy paper and wrinkles occurring on the original
documents during SPF operations were discovered in sample machines before mass
production. To alleviate this problem, the values of the resistance factor adjustment
settings (simulation 51-2) when shipped from the factory have been changed.
No. : SP-1880
3.Description: Changes in each of the resistance factor settings
(Old) ( New )
Resistance fa ct or for cassette
paper feed operations: 50 → 22 (to alleviate problems of “Z”
Resistance factor for SPF operations: 50 → 25
4.Action: From the start of mass production
2. Measures to prevent the AC relay harness from coming in contact with the fan duct

The values have been changed to 30
to improve slant feeding of A4 sized
paper since January 1995 production.

2.General: The upper frame fan duct sometimes raised up during the assembly process of the
machine, a problem caused when the head of the wire band attached to the AC relay
harness came in contact with the duct. Also, there was a possibility of the wires of the
relay harness separating, and becoming snagged in the section of the fan duct with the
fixing screws. To alleviate these problems, UL tape has been wrapped around the
harness.
3.Description: UL tape has been wrapped at locations ➀ and ➁ in the figure shown at right.
➁ Wrapped UL tape
The wires are wrapped so that they do not separate.
➀ The wire band has been
changed to UL tape.
